Hey Guys, 

So I've got a .Net Core 2.1 MVC application that we have been using for a while now. We wanted to switch over some of the reports that we had in the application to using Telerik reports. I figured this wouldn't be an issue since I implemented this same basic logic inside of a winform application that we have.

So I added a Telerik Reporting R1 2020 project to the solution and created a report. When I try to add an image to the picturebox that I have on the report for the logo either through the ellipses on the picturebox properties or by setting the picturebox.Value to a resource file that I set I get an error saying 'Cannot read resources that depend on serialization.' 

I get this error as soon as I try to create a new Report object in my class. 

So I figured that I would set the value of the picturebox to an image that I would get from Image.FromFile("file path here"). After I do that, I get an error that says 'cannot load file or assembly System.Drawing.ImageConverter'. 

This error gets popped as soon as I try to render the report using ReportProcessor.RenderReport to render a pdf version of the report. 

Now I've tried adding the System.Drawing.Common and System.Drawing.Primative nuget packages to the .Net Core application with no prevail. 

Has anyone else ran into this problem or know how to get the image to set on the picturebox? My image type is a jpg. 

Hello,

 

I used telerik:ReportViewer control in my application which is  developed by C# and WPF. It works well on my own computer(Windows 10), but it crashed immediately when it runs in win7. 

 

The detail info of my develop environment: Window 10 Pro (Version 1903)、 Visual Studio 2019

The detail info of my project：Telerik_UI_for_WPF_2019_1_116、Telerik_Reporting_R1_2019_13_0_19_116、.NET Framework 4.5

The detail info of my test environment: Window 7 Enterprise (x64, SP1),  .NET Framework 4.5.2 DevPack (I also tried 4.5.2 Full Version, still crashed)

 

The source code of my project is shown below. In order to find the cause of issue, there is only a report viewer control left.

 

Here is the error info when it crashed in win7(after i click the button):

 

Then I used DispatcherUnhandledException in my code to catch the exception, and find a  XamlParseException was throwed in reportviewer control. The detail info of this exception is too lang. So i attach the exception image at the end.

 

My application works well in win7 when i use telerik report 2014Q1. Not long ago, i upgraded it to 2019Q1, and then it crashed like that.

Hope for your advise. Thanks.

 

Our company has a client that uses Telerik Reporting. They are not using the Telerik Reporting service. They are using the reporting DLL and rendering the reports on their web server. This is how the ReportServiceConfiguration is initialized:

ReportServiceConfiguration = new ReportServiceConfiguration
{
    HostAppId = "Html5App",
    Storage = new FileStorage(),
    ReportResolver = new TelerikReportResolver(MDBReportHelper.GetReportTemplatesPath()),
    WorkerCount = 10
};

The application works as expected when running on a local machine (we can see an increase in pages being rendered in parallel, when we increase the workerCount property). However, the client reports that when deployed to their QA server, it generates only 2 pages at a time, no matter the value set to the workerCount property, and they would like to improve that. The configuration of their QA machine is as follows:

OS: Windows Server 2012 R2
CPU: 8 vcpu's - Intel Xeon CPU E5-2673 v4 @ 2.30GHz
RAM: 56GB

Their web app is running on a separate App Pool in IIS.

Do you know if there is any way to increase the number of pages, generated in parallel?

Hello,

I am currently trying out Telerik reporting and using.net standard for report's source, I followed the suggested ntier design of this thread https://www.telerik.com/forums/net-core-class-library-as-an-objectdatasource, passing dummy collection is easy however implementing ADO for .NET Standard returns assembly issues, do you have examples of .net standard project that uses ADO.NET?

If you try to create a task through the scheduling function of the report server, an error such as the attached image occurs.
Agent is running, and looking at the log taken by Agent, it appears as below.
Please tell me which part to check.

I want to limit table items display in per page, such as 4, I used RowNumber(), but it had no effect.

Hi,

I have a parameter that controls the visibility of page footer called "Show only page footer on the last page".

I also have a group footer on top of the page footer containing a HtmlTextBox with some custom footer texts, since the page footer can't grow during render it is placed in the group with PrintAtBottom set to true.

The group footer should also be hidden when page footer i hidden. It seems to work when i set the group footer to PrintOnEveryPage = false and when i set the GroupFooter.Visible = PageFooter.Visible inside of PageFooter_DataBound.

But,

This fails when i want to render multiple reports like 2 invoices and when the report engine renders a Empty page. Then i figured that is should control the visibilty of the "footers" by checking PageNumber = PageCount aswell but it looses the PageNumber and PageCount on this empty page. So i cant tell if it is the last page or not.

 

How to encounter this issue?

Good evening,

I'm trying to create a report with .net in MVC but the data comes from a soap WSDL, so I pass the query result to an Object Data Source in the controller and assign it to the report Viewer in the view but not displays the report.

 

  <div class="container">

            // Creating a new report

            Telerik.Reporting.TypeReportSource reportsource = new Telerik.Reporting.TypeReportSource() { TypeName = "ReportLibrary.OdioEsteProyecto, ReportLibrary" }; //
            Telerik.Reporting.ObjectDataSource datasSource = Model.ods; //this ods is a  ObjectDataSource variable who came from the model 

            if (datasSource != null)
            {
                <telerik:ReportViewer ID="MyReportViewer"
                                      ReportSource=reportsource
                                      ObjectDataSource=datasSource
                                      runat="server"
                                      High ="100%"
                                      Width="100%"
                                      DocumentMapVisible="False"
                                      ParametersAreaVisible="False"
                                      ShowDocumentMapButton="False"
                                      ShowHistoryButtons="False"
                                      ShowNavigationGroup="True"
                                      ShowParametersButton="False"
                                      ShowPrintPreviewButton="False"
                                      ShowRefreshButton="False"
                                      Skin="WebBlue"
                                      Visible="True">

                </telerik:ReportViewer>
          }

    </div>

 

HELP

Hi Team,
I am using Trial version of Telerik Reporting (v8.2). In that I am getting following issues,

1. I am binding the table data by using NeedDataSource Event. It's binding the data well, but the table is keep on repeating many times, even I am having Table in Report header page and made data source property of Report as NONE.

2. I have imported External XSLT into my report and assigned Style name to particular Header. Style is getting updated in Design time, but while running the application in browser it is not running.

Kindly clarify the details ASAP.

Regards,
Ram
